just a question... for what resolutions/frame rates combinations is --pic-struct required?

Thanks. One more question. If i have a 480p24 source how can i produce a blu-ray compatible stream? i mean, should i convert the framerate to 29,976? in that case how should i set the --pulldown option?

ok, so i should set something like --pulldown 32 --fake-interlaced --pic-struct ... etc.

the problem is more like 24fps and 23.976 fps are usually referred as 24 fps...
so that's more a user problem than mine (i asked all those questions coz im creating megui presets for BD encoding).

x264 command line check
Hi all,
I have a Huffyuv YV12 avi (1920x1080p @23.976fps) that I wish to encode to H.264 using x264. I'm interested in Blu-ray compliance, so looked around the forum and found this page: http://sites.google.com/site/x264bluray/ I'm thinking of using the command line: Code:
x264 --bitrate XXXXX --preset veryslow --tune film --weightp 0 --bframes 3 --nal-hrd vbr --vbv-maxrate 40000 --vbv-bufsize 30000 --level 4.1 --keyint 24 --b-pyramid strict --slices 4 --aud --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --sar 1:1 --pass 1 -o out.264 input.file 1. I recall that for MPEG2 standard def encodes, a rule-of-thumb for bitrate is... Avg: 6000 Kbps, Max: 8000 Kbps, Min: 2000 Kbps (...assuming 720x480p @23.976fps) What rule-of-thumb bitrates are used for high-def H.264 encodes (1920x1080p @23.976fps)? 2. When encoding MPEG2 for DVD authoring, 23.976fps sources need to include pulldown flags to set the framerate to 29.97fps (soft-telecine) in NTSC-land. Does an H.264 encode need to have pulldown flags to achieve soft-telecine as well? Does the command line need to be revised to invoke pulldown? 3. MPEG2 encoders can often be configured to have the MPEG2 output be either in dropframe timecode format or non-dropframe timecode format. Does x264 have this capability available as a command line switch? Thank you very much for your help. Last edited by Avisynth_challenged; 22nd July 2010 at 20:54.

1. There's no general rule for bitrate. You can go up to 40 Mbps if necessary, but you need to adhere to VBV. For 23.98p if you have a lot of space to waste, you can have an average bitrate of 35 Mbps and a max of 40 Mbps (just as example)
2. For HD sources, 23.98/24p are allowed without any soft-pulldown (this doesn't depends by h.264, but BD specs. You can have the same using MPEG2 or VC1 sources). For SD primary-video you need soft pulldown because only 50i/59.94i are allowed. |

I suggest for 1920x1080p , 23.976fps you try 7000 bitrate, and also do another encode at 10000 (both with exactly the same settings). Compare them with each other and with the source. Try increments of 2000 after that; but in addition to bitrate of course you could consider any other x264 settings or what you might have going on processing-wise before x264 encodes it.

According to the first post in this thread the SAR for 720x576 resolution should be 16:11. My standalone (SONY 360) plays it back at 64:45 however, i.e. a picture with a SAR of 16:11 and flagged as 16:11 in the stream is slighly sqeezed on playback.
It's not a big issue, but has anyone seen a Blu-Ray standalone player which really obeys the SAR as signalled in the stream? |
